When you're are a prick, generally nobody gives a damn what you say. Haven't you noticed that on the many other threads where you are a prick to people and they tell you that?
Go ahead and type all you want, you're still a prick. You've already made it clear.
But it sure is nice to have you confirm a.050" shoulder ain't needed. What a damned relief. Ok, the prick says, no problem with the 9/16 threads on the 30 Cal TikkaT3X Lite.
Besides coming up with that 0.660" shoulder!
To him a discussion board is, he speaks and you damned well better listen. Piss off Yondeprick.
So, how's about 9/16-28 (or 9/16- 24) threads and 30 cal? A bit less meat than industry accepted 1/2-28 and 22 cal, depending on one's math prowess .. Ok? Can we work with that on the T3X Lite?
If you made an effort to learn this stuff instead of trying to make it up on your own, you'd see that 9/16-24 threads
are an industry standard size for hunting profile barrels, as well as 40 cal pistol barrels. As I already said earlier in this thread. And it's right there in that TB thread spec a few posts above, and a couple other manufacturers publish specs for them as well. A shoulder of about .660" is generally recommended. But I'm sure you'll need responses from a couple other people before you listen...
